What to do if National Mower 99500500-8400 Lawn Mower tractor will not move?
If your National Mower Lawn Mower tractor won't move, first check that the parking brake is not engaged. Then, verify the towing (free-wheeling) valve is fully closed (in the down position). Lastly, inspect the linkage from the traction pedal to the pump control mechanism, ensuring all linkages are completely attached.
What to do if the reel will not turn on my National Mower 99500500-8400?
If the reel on your National Mower Lawn Mower won't turn, start by checking for any debris jammed between the reel and bedknife. Next, check for proper belt tension, noting that belt tension is not adjustable. Test the wing mower H-frames to ensure they slide easily, lubricating if needed. Also, check the rear mower belt tension idler to ensure it moves freely. Finally, inspect the drive belts between the engine clutch and countershaft pulley to ensure the spring-loaded idler moves freely; replace the belt if slippage persists due to wear or stretch.
